THOMAS YARBROUGH, OF PHILADELPHIA, PENNSYLVANIA;

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 580,748, dated April13, 1897. Application tiled May 29, 1896.r Serial No. 593,593. (Nomodel.)

T0 all whom, it may concern.-

Be it known that I, THOMAS YARBROUGH, a citizen of the United States,residing in the cityand county of Philadelphia,State of Pennsylvania,have invented a new and useful Improvement in Refrigerators, whichimprovement is fully set forth in the following speciiication andaccompanying drawings.

My invention relates to refrigerators; and it consists of thecombination and arrange ment of parts hereinafter set forth and claimed.

Figure l represents a front elevation of a refrigerator embodying myinvent-ion. Fig. 2 represents a rear elevation of said refrigerator, theback being removed and a part of the upper portion of the same beingshown in sections. Fig. 3 represents aviewin which the front of therefrigerator is removed, showing the construction and location of thecooling-chamber, iltering device, and the milk and cream holding tank orcompartment and its adjuncts. Fig. 4c represents on an enlarged scale aperspective view of the milk and cream holding compartment and itsadjuncts in detached position. Fig. 5 represents a section on line .frFig. 3, showing the general construction and arrangement of the coilswhich convey the cooled and filtered water to the jacket surrounding themilk-compartments.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates the refrigerator-casing, thesame being provided with suitable doors B, which may be of any usualconstruction.

C designates a chamber or compartment in the upper portion of thecasing, in which the ice `or other cooling medium D is adapted to beplaced and to thereby cool the chambers L' and M' of the refrigerator.

E designates a filter which is located near an end of said compartmentC, said iilter consisting of the perforated upright plates F andsuitable filtering material G therebetween.

H designates a chamber formed in the upper portion of the refrigerator,into which the 'water J, which has been filtered, is adapted to flow,said filter being intermediate the compartments C and H. n

K designates a pipe which extends laterally from the compartment H andis connected to the depending branch L, which leads to the coil M.

N designates a support for said coil M, which latter is connected bymeans of the depending branch P with the coil Q, which is mounted on thesupports Q'.

R designates an upright branch leading from said coil Q to the interiorof the compartment S, the upper portion of said branch R being providedwith a cock" X and the branch R', which is controlled by a suitablevalve and leads to the exterior of the refrigerator, as indicated inFig. 1, whereby the cooled and filtered water can be readily withdrawn.

T designates a tank in which the chamber S, which receives the cooledand iiltered water, is located, the latter being drained by means of thepipe U, which is provided with a valve W, said pipe communicating withthe drain-pipe V.

Y' designates a tank contained within the chamber S, which is providedwith a suitable cover and contains withinh it the telescoping tubes Z,A', and B', the general construction and arrangement of the above partsbeing evident from Figs. 3 and 4, the tubes Z, A', and B being movablerelative to each other, so that as the level of the milk containedwithinV the tank Y lowers the tubes Z or A can be lowered accordingly,so as to always convey away only the cream at the surface, said tubebeing readily adjusted vertically by means of the rod D2, the creambeing readily removed by means of the conduit C', as is evident fromFigs. l and 4.

D' designates a valved conduit which leads to the exterior of the casingA from the lower portion of the tank Y, through which the milk iswithdrawn.

Within the casing and below the ice and water chambers are arranged thestorage chambers or compartments L and M', the same having surroundingair-spaces, in which are located the pipe K, coil M, and branch L.

The operation is as follows: The ice or similar material D serves tocool the adjacent compartments, which may be utilized for any desiredpurpose. The water resulting from the melting of the ice, after beingfiltered, is conducted through the intermediate pipes to IOO the tank S,the iiltered water also being withdrawn Jthrough the branch R', ifdesired, and used for drinking purposes. The cream can be at .all timeswithdrawn, no matter how low the surface of the milk gets, bymanipulating the tubes Z, A', and B', and the milk and creamrespectively can be withdrawn through the conduits C and D', as isevident. The water also exercises cooling effect upon the materialscontained in the compartments L and M', as is evident.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A refrigerator having an ice-chamber in the upper part thereof, withsurrounding airspaces on its sides and bottom, a filteringchamber at oneend of said ice-chamber with a cold-Water-receiving chamber,storage-chambers arranged in said casing, with surrounding air-spaces, apipe leading from said cold- Water chamber andA provided with coils insaid air-spaces between said storage-chambers and passing around saidchambers and discharging outside of said casing.

2. A refrigerator, having in its upper part a compartment withice-ltering and water chambers therein, storage-chambers arranged inrows with surrounding air-spaces, a pipe leading from said cold-Watercompartment and having coils in said air-spaces provided with suitablesupports between said storagechambers, a compartment within said casinginto which said pipe empties and a pipe leading from said compartment-tooutside the said casing.
